. Manama srs'rnm form of apparatus embodying my invention.

Fig. 2 is a partial lan .view .of the same. Fig. 3 is an enlarge plan view ofthe guide and tilting doors in the delivery portion thereof; Fig. 4 is a cross section of'the guide and chain, on the line IV-IV of Fig. 3; Figs. 5 and 6 are detail views of the chain and dog which I preferably employ, and Fig. 7 is an enlarged section of the lower runway or track, taken on the line VII-VII of Fi .1.

My invention relates to the si e transferring of metal in steel mills and more especially to the side transfer of Inetalbeing rolled from one pass to another pass located at the side thereof, and either at the same or a different level. The apparatus may also be applied to hot bedpractice or to the side transfer of metal on supports, whether grouped or not.

In the drawings, in which I show my invention as applied to the side transfer of metal from one roller table in line with the.

gear connections 6 and 7 with the shafts ofthe table rollers.

At desirable intervals apart I provide the upper guide-ways for the sprocket chains 8,

these guideways preferably consisting of two channel shaped sections with wider lower flanges, the flanges projecting toward each other. These channels may be secured to and supported u on the side I-beam members 9 of the r0 ler tables, and preferably terminate in bell-shaped cast sectlons 10 at each end. The intermediate portion of the guide-way extends upwardly at an angle, as

shown in Fig. 1, to transfer the metal from Specification of Letters Patent. Application filed April 4. 1907. Boris-1N0. 366'375.

one level to the other level during its side movement.

The sprocket chains en age sprocketwheels lland 12, mounted on s afts 13 and 14 outside the roller tables, the shaft 13 adjacent to the delivery. table being driven by any suitable connections, so as tolexert a pull on the upper-portion of the chain. The chain, in its lower ath', is supportedupon a long}.-

tudinal i e 15, and the shaft 14' may provide with adjusting devices to regulate the tension on the chains. p v

The chains may be of any desirable form, but are preferably constructed as shown in Fi s. 5 and 6, two links alternating with one linIr; and rollers 8 being employed to carry the chains, the rollers traveling between theflanges 8 of the flanged beams 8". The lower flanges form tracks for the rollers, and the upper ones serve to hold the chains down to their-proper plane of movement. I preferably employ two of the dogs 16 with the v apparatus s wn, each dog bein in the form 0 a bell-crank pivoted to the c ain-pm between two ofthe links, and bein of U-shape with its lower legs straddling t e links and connected by a cross-bar below them. This revnts the dog from being swun forwardly eyond it's upright position, whi e the two lower legs rest 11 on the inner flanges of the channel track w ich hold it in upright position, except where these flan es are cut away to deposit the metal. In t e form shown,

the track through its delivery portion between the rollers 3 is cut away in its bottom,

and the bottom is made in separate sections or doors 17, carriedon brackets 17 extendin around the guide-way and pinned or 0t erwise secured each to a se arate rock shaft 18, which is capable of en wise-movement I in its bearings 18'. In the form shown, the

' rollers 3 are adapted to feedthree asses, and

the guide-way bottom is preferab y made in three parts, any one, of which may be dropped toallow dropping of the dog'at this point.

The bottom sect ons or doors are held elevated or closed by lugs 19, which rest upon ledgesor IOjBGtlOIis 19"'(see Fig. 4). To

release an drop any door, the corresponding shaft 18 is rocked to raise the lug 1 9 oil fromthe shelf 19". Said shaft is then moved endshown in full lines at the right hand side of In the operation of the apparatus the chain mechanism is normally still. When a metalsection is delivered on the rollers 2, the operator startsthe shaft 13 into motion and the chain dogs entering the left-handbell mouths of the guides are-sup orted on the guide-way -to prevent their ackward tilting. In the continued travel'of the chains these dogs push the metal which slides on the. top of their channel guide -.ways, until the dogs reach the lower floorsections of the guide at the table 3, -Wi1811 the dogs being no longer supported, will swing backwardly into. the position shownat the upper right-hand of Fig. 1, thus leaving the .metal at the desired, oint. The travel of the chains'may then e stopped by the operator, and when the next section arrives on the roller-table 2 he will again start the chains into motion,

when the next dog will act in the same manner.

The advantages of the invention will be apparent to those skilled in the art. The

use of the chains with swinging do s enables us to stop the metal at any desire point in the side transfer and without the use of complicated mechanism. The floor or bottom' sections of the guide may be cut out or dropped at any desired point or points where the metal is to be stopped or temporarily detained; the sections may be grouped between the two tables, if desired, and the dogsflu'sed to feed to one side of the group and take away from the other side, and again leave at the-roller table, or not, as desired. Either for both of these operations may be carried out by simply providing the removable floor sections or dog supports where it may be desired to stop the metal; or by cutting away these dog. supports if no admstment is desired in this regard. The operations are easily and quickly carried out, and the ap a ratus is not liable to get out of order. The chainguides serve as skids or supports for the metal in its sidewise movement, and-prevent jumplin upward of the chain in the 0 its travel.

p e PM d ny number of do s may be employed; the a shape and arrangement'of the dogs may be varled, as well as the dog supports or means for holding the dogs elevated; the upper path paratus; and other changes may be ma e without departing from my invention.

I claim':

1. In metal transfer apparatus, a continuous flexible carrier, dog {pivoted thereto, means for normally holding the dog in its operative position, and means at difierent points inthe path of movement of the dog whereby it may becausedto swing at any one of said points to stop themetal; substantially as described.

2. In metal transfer apparatus, a carrier chain, a dog pivoted thereon, means for normally holding the dog in its ,operative position, and means at different points in the path of movement of the dog whereby it may be caused to swing at' any oneof said points to stop the metal, substantially as described.

. 3. In metal transfer apparatus, a chain, a dog'pivoted thereon, an a dog-support having removable sections arranged to change the point where the do tilts to release the metal; substantiallyas escribed.

- 4. In metal transfer mechanism, a continuous chain having dogs pivoted thereto, hinged supports for the dogs at different points in the travel of the chain, and means for dropping anyone of said supports to cause the dogs to tilt; substantially as described.

5. In metal transfer mechanism, a continuous carrier chain having dogs ivoted thereto, a bottom support for said dogs havin hinged sections or doors, supports for said sections or doors, and means for disengaging the sections or doors from their supports; substantially as described.

' 6. In metaltransfer mechanism, a continuous carrier chain having dogs ivoted thereto, a bottom support for sai dogs havin hinged sections or doors, supports for said sections'or doors, and endwise movable rock shafts carrying the sections or doors, substantially as described.

Intestimony whereof I have hereunto set my hand.
